Arrrgg! I just tried Swift Backup as a restore method for a secondary user profile, and it won't work, it just says its not supported!
I've confirmed that Seedvault is broken now... I've tried with 3 different USB sticks, 1 very high quality expensive Samsung stick, a Kingston one and a Patriot one, all bought within the last 3 months. The Patriot one was working PERFECTLY before the last Seedvault update. Every. Single. Time. Now it will back up app data, but not the APK's. I've confirmed this because on first restore it just shows a bunch of red signs, but if you do a second restore after installing your apps it will restore the data for those apps.
The Seedvault backups take exactly as long as before. They also take as much space as before. Another change since the last update is that so far 1/3 times when testing a backup, it gives me the "no backups can be found at this location" screen.
That's all the info I can think to give in my report... Considering that Swift Backup, the only good third party backup program doesn't work on user profiles, Seedvault working is even more of a necessity, especially since it was just working so well! Perhaps the last update can be rolled back?
Thank you all for all your hard work! I'm teaching myself how to compile to OS right now, perhaps I could help with this task...
